|Fringe theory in a nutshell: To maintain a neutral point of view, an idea that is not broadly supported by scholarship in its field must not be given undue weight in an article about a mainstream idea. More extensive treatment should be reserved for an article about the idea, which must meet the test of notability. Additionally, when the subject of an article is the minority viewpoint itself, the proper contextual relationship between minority and majority viewpoints must be clear.|

In Wikipedia parlance, the term fringe theory is used in a very broad sense to describe an idea that departs significantly from the prevailing views or mainstream views in its particular field. Because Wikipedia aims to summarize significant opinions with representation in proportion to their prominence, a Wikipedia article should not make a fringe theory appear more notable or more widely accepted than it is. Statements about the truth of a theory must be based upon independent reliable sources. If discussed in an article about a mainstream idea, a theory that is not broadly supported by scholarship in its field must not be given undue weight, and reliable sources must be cited that affirm the relationship of the marginal idea to the mainstream idea in a serious and substantial manner.
There are numerous reasons for these requirements. Wikipedia is not and must not become the validating source for non-significant subjects. Wikipedia is not a forum for original research. And for writers and editors of Wikipedia articles to write about controversial ideas in a neutral manner, it is of vital importance that they simply restate what is said by independent secondary sources of reasonable reliability and quality.
The governing policies regarding fringe theories are the three core content policies, Neutral point of view, No original research, and Verifiability. Jointly these say that articles should not contain any novel analysis or synthesis, that material likely to be challenged needs a reliable source, and that all majority and significant-minority views published in reliable sources should be represented fairly and proportionately. Should any inconsistency arise between this guideline and the content policies, the policies take precedence.
We use the term fringe theory in a very broad sense to describe an idea that departs significantly from the prevailing views or mainstream views in its particular field. For example, fringe theories in science depart significantly from mainstream science and have little or no scientific support. Other examples include conspiracy theories and esoteric claims about medicine. Scholarly opinion is generally the most authoritative source to identify the mainstream view. However, there are at least two caveats: not every identified subject matter has its own academic specialization, and the opinion of a scholar whose expertise is in a different field should not be given undue weight.
When discussing topics that reliable sources say are pseudoscientific or fringe theories, editors should be careful not to present the pseudoscientific fringe views alongside the scientific or academic consensus as though they are opposing but still equal views. While pseudoscience may, in some cases, be significant to an article, it should not obfuscate the description or prominence of the mainstream views.
Not all pseudoscience and fringe theories are alike. In addition, there is an approximate demarcation between pseudoscience and questionable science, and they merit careful treatment.
To determine whether something is pseudoscientific or merely an alternative theoretical formulation, consider this: Alternative theoretical formulations generally tweak things on the frontiers of science, or deal with strong, puzzling evidence—which is difficult to explain away—in an effort to create a model that better explains reality. Pseudoscience generally proposes changes in the basic laws of nature to allow some phenomenon which the supporters want to believe occurs, but lack the strong scientific evidence or rigour that would justify such major changes. Pseudoscience usually relies on attacking mainstream scientific theories and methodology while lacking a critical discourse itself (as is common among Biblical creationists), relies on weak evidence such as anecdotal evidence or weak statistical evidence (as for example in parapsychology), or indulges a suspect theoretical premise (such as the claims of water memory made by advocates of homeopathy).
Reliable sources are needed for any article in Wikipedia. They are needed to demonstrate that an idea is sufficiently notable to merit a dedicated article about it. For a fringe view to be discussed in an article about a mainstream idea, independent reliable sources must discuss the relationship of the two as a serious and substantial matter.
Reliable sources on Wikipedia may include peer-reviewed journals; books published by university presses; university-level textbooks; magazines, journals, and books published by respected publishing houses; and mainstream newspapers. Academic and peer-reviewed publications are usually the most reliable sources in areas where they are available, but material from reliable non-academic sources may also be used in these areas.
Subjects receive attention in Wikipedia in proportion to the level of detail in the sources from which the article is written. For example, if the only references to a particular subject are in news sources, then a level of detail which is greater than that which appears in these news sources is inappropriate, because Wikipedia policy prohibits original research. The no original research policy strongly encourages the collection and organization of information from existing secondary sources, and allows for careful use of primary sources.
The best sources to use when describing fringe theories, and in determining their notability and prominence, are independent reliable sources. In particular, the relative space that an article devotes to different aspects of a fringe theory should follow from consideration primarily of the independent sources. Points that are not discussed in independent sources should not be given any space in articles. Independent sources are also necessary to determine the relationship of a fringe theory to mainstream scholarly discourse.
Inclusion and exclusion of content related to fringe theories and criticism of fringe theories may be done by means of a rough parity of sources. However, if an article is written about a well-known topic, it should not include fringe theories that may seem relevant but are only sourced by obscure texts that lack peer review. Note that fringe journals exist, some of which claim peer review. Only a very few of these actually have any meaningful peer review outside of promoters of the fringe theories, and they should generally be considered unreliable. Examples of unreliable journals include, but are not limited to: The Creation Research Society Quarterly, Homeopathy, and the Journal of Frontier Science (which uses blog comments as its supposed peer review).
In an article on a fringe topic, if a notable fringe theory is primarily described by amateurs and self-published texts, verifiable and reliable criticism of the fringe theory need not be published in a peer reviewed journal. For example, the Moon landing conspiracy theories article may include material from reliable websites, movies, television specials, and books that are not peer reviewed. By parity of sources, critiques of that material can likewise be gleaned from reliable websites and books that are not peer reviewed. Of course, for any viewpoint described in an article, only reliable sources should be used; Wikipedia's verifiability and biographies of living persons policies are not suspended simply because the topic is a fringe theory.
Parity of sources may mean that certain fringe theories are only reliably and verifiably reported on, or criticized, in alternative venues from those that are typically considered reliable sources for scientific topics on Wikipedia. For example, the lack of peer-reviewed criticism of creation science should not be used as a justification for marginalizing or removing scientific criticism of creation science, since creation science itself is almost never published in peer-reviewed journals. Likewise, views of adherents should not be excluded from an article on creation science solely on the basis that their work lacks peer review. Other considerations for notability should be considered as well. Fringe views are properly excluded from articles on mainstream subjects to the extent that they are rarely if ever included by reliable sources on those subjects.
The prominence of fringe views needs to be put in perspective relative to the views of the entire encompassing field; limiting that relative perspective to a restricted subset of specialists or only among the proponents of that view is, necessarily, biased and unrepresentative.
Wikipedia is meant to be a tertiary source of information, summarizing the information gleaned from secondary sources, and in some cases from primary sources. Primary sources about research and investigations should only be used to verify the text and should not be relied on exclusively as doing so would violate Wikipedia's policies on original research. In the case of obscure fringe theories, secondary sources that describe the theories should be carefully vetted for reliability.
While proper attribution of a perspective to a source satisfies the minimal requirements of Wikipedia's neutral point of view, there is an additional editorial responsibility for including only those quotes and perspectives which further the aim of creating a verifiable and neutral Wikipedia article. Quotes that are controversial or potentially misleading need to be properly contextualized to avoid unintentional endorsement or deprecation. What is more, just because a quote is accurate and verifiably attributed to a particular source does not mean that the quote must necessarily be included in an article. The sourced contribution must simply aid in the verifiable and neutral presentation of the subject.
For example, in the article about Bigfoot, a verifiably attributed and accurately preserved quotation might take the following form:
The Bigfoot Field Researchers Association has stated, "Scientists from various disciplines put the most compelling sasquatch evidence to the test. Collectively their conclusions are ground-breaking. There is now scientific proof for the existence of a giant primate species in North America – a species fitting the descriptions of sasquatches (bigfoots)."
Including such a controversial quote needs to be carefully contextualized as a particular point of view. Simply including such a statement in the lead or in a section on scientific evaluation of Bigfoot claims is potentially misleading, non-neutral, and lacking in verifiability. The quote should only be included if it can be contextualized in a verifiable and neutral sense as a point of view of the Bigfoot Field Researchers Association and not necessarily a factual statement. The consensus of editors may even be to not include the quote at all.
The careful use of sources is vital when writing about criticism of fringe theories. Since fringe theories may be obscure topics that few non-adherents write about, there may only be a small number of sources that directly dispute them. Care should be taken not to mislead the reader by implying that, because the claim is actively disputed by only a few, it is otherwise supported. Particularly harsh criticism should be attributed – "Philosopher A. C. Grayling dismisses intelligent design as 'a little driblet of childish ignorance; a mark of mankind's infancy'" – while simple facts – "humans and chimpanzees evolved from a common ancestor" – are best left stated simply as facts rather than recast as opinions. Be careful not to use in-text attribution carelessly to imply that only the named sources would agree. A careful use of words and the adoption of a disinterested tone will ensure that a reader is not spoonfed opinions as facts and vice versa.
For a fringe theory to be considered notable, and therefore to qualify for a separate article in Wikipedia, it is not sufficient that it has been discussed, positively or negatively, by groups or individuals – even if those groups are notable enough for a Wikipedia article themselves. To be notable, a topic must receive significant coverage in reliable sources that are independent of the subject. Otherwise it is not notable enough for a dedicated article in Wikipedia.
A fringe subject (a fringe theory, organization or aspect of a fringe theory) is considered notable enough for a dedicated article if it has been referenced extensively, and in a serious and reliable manner, by major publications that are independent of their promulgators and popularizers. References that debunk or disparage the fringe view can be adequate, as they establish the notability of the theory outside of its group of adherents. References that are employed because of the notability of a related subject – such as the creator of a theory – should be given far less weight when deciding on notability. Due consideration should be given to the fact that reputable news sources often cover less than strictly notable topics in a lighthearted fashion, such as on April Fool's Day, as "News of the Weird", or during "slow news days" (see junk food news and silly season). Even reputable news outlets have been known to publish credulous profiles of fringe theories and their proponents, and there continue to be many completely unreliable sources masquerading as legitimate.

Just because an idea is not accepted by most experts does not mean it should be removed from Wikipedia. The threshold for whether a topic should be included in Wikipedia as an article is generally covered by notability guidelines. The complicated relationship between the level of acceptance of an idea and its notability is explored below.
Articles which cover controversial, disputed, or discounted ideas in detail should document (with reliable sources) the current level of their acceptance among the relevant academic community. If proper attribution cannot be found among reliable sources of an idea's standing, it should be assumed that the idea has not received consideration or acceptance; ideas should not be portrayed as accepted unless such claims can be documented in reliable sources. However, a lack of consideration or acceptance does not necessarily imply rejection, either; ideas should not be portrayed as rejected or carry negative labels such as pseudoscience unless such claims can be documented in reliable sources.
Ideas that have been rejected, are widely considered to be absurd or pseudoscientific, only of historical interest, or primarily the realm of science fiction, should be documented as such, using reliable sources.
Ideas that are of borderline or minimal notability may be mentioned in Wikipedia, but should not be given undue weight. Wikipedia is not a forum for presenting new ideas, for countering any systemic bias in institutions such as academia, or for otherwise promoting ideas which have failed to merit attention elsewhere. Wikipedia is not a place to right great wrongs. Fringe theories may be excluded from articles about scientific topics when the scientific community has ignored the ideas. However, ideas should not be excluded from the encyclopedia simply because they are widely held to be wrong. By the same token, the purpose of Wikipedia is not to offer originally synthesized prose "debunking" notable ideas which the scientific community may consider to be absurd or unworthy. Criticisms of fringe theories should be reported on relative to the visibility, notability, and reliability of the sources that do the criticizing.
Wikipedia is also not a crystal ball: While currently accepted scientific paradigms may later be rejected, and hypotheses previously held to be controversial or incorrect sometimes become accepted by the scientific community (e.g., plate tectonics), it is not the place of Wikipedia to venture such projections. If the status of a given idea changes, then Wikipedia changes to reflect that change. Wikipedia primarily focuses on the state of knowledge today, documenting the past when appropriate (identifying it as such), and avoiding speculation about the future.
One important barometer for determining the notability and level of acceptance of fringe ideas related to science, history or other academic pursuits is the presence or absence of peer-reviewed research on the subject. While a lack of peer-reviewed sources does not automatically mean that the subject should be excluded from Wikipedia, there must be adequate reliable sources to allow the subject to be covered in sufficient detail without engaging in original research. Care should be taken with journals that exist mainly to promote a particular viewpoint. Journals that are not peer reviewed by the wider academic community should not be considered reliable, except to show the views of the groups represented by those journals.
Peer review is an important feature of reliable sources that discuss scientific, historical or other academic ideas, but it is not the same as acceptance by the scientific community. It is important that original hypotheses that have gone through peer review do not get presented in Wikipedia as representing scientific consensus or fact. Articles about fringe theories sourced solely from a single primary source (even when it is peer reviewed) may be excluded from Wikipedia on notability grounds. Likewise, exceptional claims in Wikipedia require high-quality reliable sources.
Many encyclopedic topics can be evaluated from a number of different perspectives, and some of these perspectives may make claims that lack verification in research, that are inherently untestable, or that are pseudoscientific. In general, Wikipedia should always give prominence to established lines of research found in reliable sources and present neutral descriptions of other claims with respect to their historical, scientific, and cultural prominence. Claims that are uncontroversial and uncontested within reliable sources should be presented as simple statements of fact – e.g. "An electron has a mass that is approximately 1/1836 that of the proton."
Claims derived from fringe theories should be carefully attributed to an appropriate source and located within a context – e.g. "There are extreme academic views such as those of Jacques Halbronn, suggesting at great length and with great complexity that Nostradamus's Prophecies are antedated forgeries written by later hands with a political axe to grind." Such claims may contain or be followed by qualifiers to maintain neutrality – e.g. "Although Halbronn possibly knows more about the texts and associated archives than almost anybody else alive (he helped dig out and research many of them), most other specialists in the field reject this view." – but restraint should be used with such qualifiers to avoid giving the appearance of an overly harsh or overly critical assessment. This is particularly true within articles dedicated specifically to fringe ideas: Such articles should first describe the idea clearly and objectively, then refer the reader to more accepted ideas, and avoid excessive use of point-counterpoint style refutations. It is also best to avoid hiding all disputations in an end criticism section, but instead work for integrated, easy to read, and accurate article prose.
Notable perspectives which are primarily non-scientific in nature but which contain claims concerning scientific phenomena should not be treated exclusively as scientific theory and handled on that basis. For example, the Book of Genesis itself should be primarily covered as a work of ancient literature, as part of the Hebrew or Christian Bible, or for its theological significance, rather than as a cosmological theory. Perspectives which advocate non-scientific or pseudoscientific religious claims intended to directly confront scientific discoveries should be evaluated on both a scientific and a theological basis, with acknowledgment of how the most reliable sources consider the subjects. For example, creationism and creation science should be described primarily as religious and political movements and the fact that claims from those perspectives are disputed by mainstream theologians and scientists should be directly addressed. Fringe theories that oppose reliably sourced research – denialist histories, for example – should be described clearly within their own articles, but should not be given undue weight in more general discussions of the topic.
Proponents of fringe theories have used Wikipedia as a forum for promoting their ideas. Policies discourage this: if the only statements about a fringe theory come from the inventors or promoters of that theory, then "What Wikipedia is not" rules come into play. Wikipedia is neither a publisher of original thought nor a soapbox for self-promotion and advertising. The notability of a fringe theory must be judged by statements from verifiable and reliable sources, not the proclamations of its adherents. Attempts by inventors and adherents to artificially inflate the perceived renown of their fringe theories, such as sock puppetry in AfD discussions, is prohibited. Efforts of fringe-theory inventors to promote their theories, such as the offering of self-published material as references, are unacceptable: Wikipedia is not an advertising venue. (See also Links normally to be avoided, Conflict of interest, Autobiography guidelines.)
The neutral point of view policy requires that all majority and significant-minority positions be included in an article. However, it also requires that they not be given undue weight. A conjecture that has not received critical review from the scientific community or that has been rejected may be included in an article about a scientific subject only if other high-quality reliable sources discuss it as an alternative position. Ideas supported only by a tiny minority may be explained in articles devoted to those ideas if they are notable.
Fringe views, products, or the organizations who promote them, may be mentioned in the text of other articles only if independent reliable sources connect the topics in a serious and prominent way. However, meeting this standard indicates only that the idea may be discussed in other articles, not that it must be discussed in a specific article. If mentioning a fringe theory in another article gives undue weight to the fringe theory, discussion of the fringe theory may be limited, or even omitted altogether. If no independent reliable sources connect a particular fringe theory to a mainstream subject, there should not even be a link through a see also section, lest the article serve as a coatrack.
Fringe theories should be discussed in context; uncontroversial ideas may need to be referred to in relation to fringe theories. Discussion of mainstream ideas should be sourced from reliable mainstream sources. Links to non-fringe articles in fringe articles can also help aid the reader in understanding and remove the threat of creating a walled garden. In contrast, many mainstream articles do not link to articles about fringe theories. This is the principle of one-way linking for fringe theories.
Note, however, that the mainstream scientific subjects are discussed and linked to in both of the above articles about fringe subjects (the Astrology article discusses astronomy, and Autodynamics discusses special relativity).
Close attention should be paid to the treatment of those who hold fringe viewpoints, since as a rule they are the focus of controversy. All articles concerning these people must comply with Wikipedia's policy on biographies of living persons (WP:BLP). Fringe views of those better known for other achievements or incidents should not be given undue prominence, especially when these views are incidental to their fame, but the WP:BLP policy does not provide an excuse to remove all criticism from a biography or to obscure a person's fringe advocacy outside of their field of expertise (see WP:PROFRINGE, WP:BLP#Balance).
There are people who are notable enough to have articles included in Wikipedia solely on the basis of their advocacy of fringe beliefs. Notability can be determined by considering whether there are enough reliable and independent sources that discuss the person in a serious and extensive manner, taking care also to avoid the pitfalls that can appear when determining the notability of fringe theories themselves. Caution should be exercised when evaluating whether there are enough sources available to write a neutral biography that neither unduly promotes nor denigrates the subject.
